Contrast to POV-Ray on Windows, POV-Ray on Linux does not contain GUI*. Just for editing, any editor is fine, however, we’d also like render images while editing. In such sense, we prefer editor with rendering function. There exist several such editors:

patch
Download from Clemens Rabe’s website and apply patch. The following command is called from a directory that contains a directory /povray-3.6.1/ and the patch file.patch -p0 < ./povray-3.6.1_LenseDistortion.patch

install/configure COMPILED_BY=”your name <email@address>”makesudo make install

phew… installation seems to be completed. For quick check, I rendered a sphere with black background. Tomorrow, I will check the lens distortion effect!!
